between USCG observations by J, Deaver and NASA and EPA imagery, and model 

 outputs. 



Current observations were obtained by AMSI by means of dye markers, 

 vertical photography, and a combination of Loran-C and fixed references. 

 These were central to the BLM support, but will also undoubtedly aid in model 

 validation efforts. Results must await return of the color film, and it is 

 anticipated that the data loss will be high because of severe weather condi- 

 tions, technical difficulties, and the experimental nature of the techniques 

 used. 



Sea surface temperature measurements were obtained with a Barnes PRT-5-S 

 IR radiometer (9.5 to 11.5 microns, linear output), which was virtually 

 identical to the one used by USCG. There were technical difficulties on the 

 first several flights, but later data should be quite good (+ 0.5°C). 



Data reduction will be confined to current and sea surface temperature 

 observations. 



2.1.2 Ship Operations 



Operations to support investigations of physical processes were con- 

 ducted from ships supported or operated by USCG, the U.S. Geological Survey 

 (USGS), the Woods Hole Oceanographic Institution (WHOI) and by the University 

 of Rhode Island. Cruise descriptions are contained in Appendix V. 



USCG had cutters stationed continuously at the wreck site from the day 

 of the grounding, December 15, 1976, until December 31. These vessels, the 

 Vigilant and Bittersweet, collected hourly surface meteorological data, 

 acquired water samples for chemical analysis, and supported many other activ- 

 ities in response to OSC requests. The USCGC Evergreen conducted a sampling 

 cruise to study the fate of the spilled oil and the cutter Spar participated 

 in the oil burning tests as well as supporting other research. 



The U.S. Geological Survey (USGS) at Woods Hole Massachusetts, chartered 

 the tug Whitefoot for implanting current meter moorings as well as acquiring 

 bottom sediment samples, and WHOI sponsored two cruises of the Ooeanus , which 

 collected water and sediment samples and implanted a current meter mooring. 

 The University of Rhode Island (URI) sponsored four cruises of the Endeavor, 

 which also collected water and sediment samples and implanted a current meter 

 mooring. 



2.2 Results of Field Efforts 



The results of the field efforts are included under six headings: map- 

 ping, physical observations, water motion measurements, oil and differential 

 oil/water velocity measurements, water mass observations, and meteorological 

 observations.
